We would like to retract this Letter. Nature previously issued an Editorial Expression of Concern (https://doi.org/10.1038/s41586-020-2756-0) after we, the authors, alerted the journal to potential problems with the matrix-assisted laser desorption/ionization time-of-flight (MALDI–TOF) mass spectrometry data. These issues undermine our confidence in the integrity of the study as a whole and we therefore now wish to retract the Letter. Our group continues to explore the synthesis of graphene nanoribbons (GNRs), but we have been unable to reproduce some of the results presented in this Letter. Careful scrutiny of the source data has identified potential problems with the manner in which the MALDI–TOF mass spectrometry data in this Letter were originally generated and processed. Specifically, the exact molecular weights (m/z calculated for [M]+ and [M + Ag]+) of GNRs 2 (Extended Data Fig. 1), 7 (Extended Data Fig. 6) and 8 (Extended Data Fig. 7) were calculated wrongly on the basis of the assumption that all carbon atoms in these GNRs were 12C (monoisotopic). In all GNRs, the exact mass peaks should appear approximately 6 to 9 mass units higher. Thus, the observed mass spectra do not match the proposed GNR structures. The isotopic patterns of some GNRs (for example, Extended Data Fig. 7c, d for GNR 8) do not match the (correct) calculated spectra. These also do not support the formation of the proposed GNR structures. The baselines (noise) of the mass spectra of GNRs 2 and 8 appear to be identical, which calls into question the integrity of the mass data. The original MALDI-TOF mass spectrometry data are unavailable and only editable secondary data exist, which also raises concerns regarding the integrity of the mass data. We regret any confusion and apologize to the scientific community.

この研究室は問題を学術誌の方に通知しただけまだよい。
OB事件（大阪大学、国立環境研究所）では小学生レベルの非常に簡単な確認と計算で削減率の正当性を確認できるのに、確認後削減率が間違っていたと意図的に虚偽記載して、嘘の情報に基づいた分析結果に全面的に変更し、結論・主旨さえ書き換える大量訂正を行った。大量訂正は原著論文の極めて悪質な捏造の隠蔽の疑いがある。
京大は再生研事件でも通報を握り潰し、隠蔽した。責任著者は今年になって捏造を認めて一部の論文を自主撤回。
調査していないなら名大が調査を行う必要があるかもしれない。
